APPARATUS FOR THE DISTRIBUTION OF ELECTRICITY.

SPECIFICATION forming part of Letters Patent No. 310,665, dated January13, 1885.

Application filed June 2, I984. (X0 model.)

1'0 all whom it may concern:

Beit known that I, Osoan G-ASSE'ITT, of Boston, county of Suffolk, andState of Massachnsetts,have invented an Improvement in Distribution ofPower, of which the following description, in connection with theaccompanying drawing, is a specification, like letters on the drawingrepresenting like parts.

My invention relates to apparatus for supplying power derived from aprime motor at a main or distributing station for the production ofelectricity at various sub-stations. The prime motoris employed to storepower preferably by accumulating a fluid under pressure, which fluid isconveyed by pipes to the various sub-stations where the electricityis tobe generated. At each of these substations there is a secondary motoradapted to be actuated by the power stored by the prime mo tor, and theapplication of power to the secondary motor is controlled by anelectro-magnet and circuit having a suitable switch orcircuit-controlling device, which may be located at any desired point,so that by operat ing the said switch the secondary motoris set inoperation and the generation of electricity begins.

The drawing shows in diagram an apparatus for distributing powerembodying this invention, the electricity generated being shown asemployed for lighting.

The prime motor at the main or power-supplying station may be of anysuitable character, as a wind or water wheel or steam-engine, the cranka of which only is shown as actuating a pump or compressing device, I),by which air or other fluid is accumulated under pressure in a mainreceptacle or tank, 0, having a distributingpipe, d, by which the saidfluid is conveyed to the various points where the power is to be used.At such points or sub-stations where the power is to be used the pipe (Iis providedwith branch pipes d, preferably having connected with themsecondary tanks or receptacles d", containing the fluid under pressure,there being check-valves d between the said main pipe and secondaryreservoirs, d. The pipe (1 enters a eontrolling device, (shown as achest, 6,) having ports fg, the former leading to a main valve cy1inder,h, and the latter to a controlling valve chamber, 2', separated from thesaid main cylinder h by a partition, ls, having a passage, It,controlled by the governingvalve, m,which is operated by anelectro-magnet, a, controlling the flow of fluid from the chamber r tothe cylinder 71, where the said fluid actuates the main valve, having atransverse port or annular groove, 0, which, when the said valve is inthe proper position, as shown in the drawing, connects the portj'withthe portf, leading to the pipe (1, which supplies the fluid foractuating the secondary motor d. The chamber '2? is constantly suppliedthrough the port {1 with fluid under proper pressure, when permitted topass through the passage 7t, to move the valve 0 against the pressure ofaspring, 1, into the position to admit the fluid to the pipe d and motord. The valve ois provided with a small passage, 0, or has a loose fit inthe cylinder h, thus permitting the fluid to escape from the saidcylinder h, but not with suliicient rapidity to materially reduce itspressure as long as it is freely admitted through the passages g and 7..hen, however, the valve m is closed and the supply of fluid thus cutofffrom the cylinder h, it quickly escapes from the said cylinder,permitting the spring 1) to force the valve 0 toward the partition ll:until the nngrooved portion of the said valve closes the port f, andthus cuts oil the supply of fluid from the motor d. The valve m is movedto open or close the passage 7;, and thus govern the position of themain valve 0 by the electro-magnet it, included in the circuit a, havinga circuit-controlling device or switch, a,

by which the said circuit may be opened or closed to govern thecondition of the magnet 92, which, as shown in this instance, retainsthe valve in open when the said magnet is e11- ergized or while itscircuit is kept closed. The secondary motor d actuates an electricgenerator, 0', which thus produces a current of electricity whenever theswitch a is closed, and ceases to operate when the said switch isopened, and the current generated maybe em ployed for any desiredpurpose, being shown in this instance as supplying alamp, t,the light ofwhich is thus controlled by the switch n".

hen,- as will generally be the case, there are a number of substationssupplied from one prime motor, the latter may be run practica-ll yconstantly to supply suflicient power to operate the secondary motorsand generators when needed, the said power being stored in the main andsecondary reservoirs c (1 until needed, and the said storage will enablethe secondary motors to be run during portions of the time with agreater consumption of power than could be supplied by the prime motorif the power were used directly therefrom without accumulation.

I claim 1. The combination of a prime motor for to the secondary motor,substantially as described.

2. The combination of a prime motor, op-

crating to accumulate a iluid under pressure, a main reservoir for saidfluid, and distributing-pipes leading therefrom, secondary resen voirsconnected with said pipes at sub-stu- ,tions where the power is to beused, second- 'ary motors and electric generators actuated magnets,circuits, and circuit-controlling del vices governing the application ofpower to the secondary motors, substantially as described.

to this specification in the presence of two sul scribing witnesses.
